[PATCH] Enable glibc builds on stable release branches

[Simon Chopin <simon.chopin@canonical.com>]

The glibc 2.37 release announcement contains an exlicit call for
distributions to track the stable release branches. In light of this, I
think it makes sense for those branches to have CI coverage similar to
the master branch.
